On three new species of the genus Criconemoides Taylor, 1936 (Nematoda: Criconematidae) from North India

Abstract

The definition of the genus Criconemoides should be extended so as to include those aberrant forms which possess slight cuticular ornamentation. Three new species of the genus Criconemoides Taylor, 1936 are described and illustrated from North India. Criconemoides aberrans n. sp. is distinctive in having 38-43 body annules, rough cuticular outgrowths on the body, 68-78 µ long spear, bluntly rounded tail, absence of spermatheca and males unknown. Criconemoides neoaxeste n. sp. has 45-49 body annules marked with faint longitudinal lines and rough posterior margins, 65-75µ long spear, rounded tail terminus, vulva located at 7th or 8th annule from the posterior end and larva having a cuticular flap with rough margins on each annule. Criconemoides macrolobatus n. sp. is distinguished by 81-86 body annules, very large oval sublateral lobes, 71-75 µlong spear, tail terminus rounded and the absence of spermatheca and males unknown.
